Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging connections are used to physically and electrically connect the energy storage device to a stationary power supply, then reliable power transfer is achieved, but the system becomes inconvenient and cumbersome
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless electromagnetic field-based power transfer system. The stationary power supply transmits power wirelessly through electromagnetic fields to the vehicle's energy storage device, eliminating the need for physical cable connections and connectors, thereby improving convenience while maintaining power transfer reliability
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium for power transfer between the stationary power supply and the vehicle's energy storage device. This intermediary enables wireless energy transmission, resolving the contradiction by providing both reliable power transfer (through controlled electromagnetic coupling) and operational convenience (by eliminating physical connections)
2Ease of operation
If wireless charging connections are used to wirelessly connect to the energy storage device, then charging convenience is improved, but safety risks and energy transfer degradation occur
Solution Approach 1:
The patent implements feedback mechanisms where the vehicle's controller communicates with the stationary power supply to monitor and adjust power transfer parameters in real-time. This feedback system ensures safe operation by detecting anomalies and preventing unsafe conditions, while also optimizing energy transfer efficiency to minimize degradation, thus maintaining reliability while providing wireless convenience
Solution Approach 2:
The patent employs dynamic adjustment of electromagnetic coupling strength and power transfer rates based on real-time conditions. The system can modulate the wireless power transfer characteristics to optimize both safety and efficiency, adapting to changing conditions to prevent energy loss and ensure safe operation while maintaining wireless charging convenience
3Stability of the object's composition
If stationary power supplies with wired connections are used, then stable power delivery is achieved, but the system complexity and safety risks increase
Solution Approach 1:
The patent replaces complex mechanical connection systems (cables, connectors, switching mechanisms) with a streamlined wireless electromagnetic power transfer system. This substitution reduces the number of moving parts and connection points, thereby reducing system complexity while maintaining stable power delivery through controlled electromagnetic fields
Solution Approach 2:
The patent designs the wireless charging system to serve multiple functions: power transfer, communication, and safety monitoring, all through the electromagnetic field interface. This multi-functionality reduces the need for separate dedicated systems for each function, thereby reducing overall system complexity while ensuring stable and safe power delivery
